Dynamic changes in lactate and blood acid-base status during cardiopulmonary resuscitation and clinical outcomes in adult cardiac arrest patients: a prospective study.

An increase in pH was also independently associated with sustained ROSC (adjusted OR 1.23 per 0.1-unit increase; 95% CI 1.03–1.48; P = 0.02), whereas associations with survival to hospital discharge and favourable neurological outcome did not reach statistical significance.
